' oft-BURNER.

. sraoe a V all whom z't mag concern:

. Be it lmown that KYLE DERIAS OBEN- SHAIN, a citizen of the United States, and. a resident of'McKinney, inthe county of Collin and State of Texas, have invented certain new and useful Improvements in Oil "Burners, of which the following is a specification. .M

invention isan improvement in oil burners, and hasfor its object to provide an economical, and easily handled burner of v the character specified, having a large capacity and wherein the burner is automatically controlled by the differential pressure between the oil and steam within the burner head.

In the drawings v V 1 Figure 1 is a front view of the improved burner; V 1

I Fig; ,6 is a section on. line 66 of Flg. 1;

Fig. 7 isa. side view with parts brolren away, showing a modified construction.

An oil feed pipe 7, from suitable source of supply, is connected with the lateral branchiofj the T .6 and a short section of pipe 8 connects the other endof the Twith a valve casing 9. A valve 10 is arranged within thiscasing for controlling the communication betweenthe pipe 8 and the cas ing. The valve has a stem llwhich extends through a stuffing box 12 at theouter end of the valve casingand is provided with a hand wheel 13for convenience in manipulating the same.

An elbow 14 is connected. with the casing 9, and extends laterally therefrom, and a Application filed February 9, 1920. Serial No. 857,241.

mately parallelwith the pipe 1 toward the burner head, and to near the burner head as shown in Fig. 1. r f I It w'll be noticed, referring to Fig. 2, that one end of the casing 9 adjacent to the pipe conical valve 10 cooperates with this seat.

The burner head shown more particularly in Fig. 4 comprises a substantially cylin .drical casing consisting of a lowersection16 and an upper section 17, which are detachably connected together by means of a tubularjstructure 18. extending axially of the casing, and integral-at its lower end with the center of the bottom of the section 16, and abutting at its upper endthe inner face 16 and 17 being cup-shaped, asshown. ,The section 17 hasa .centralopening in its top,

the plug engaging the tubular structure 18. The pipe 1 communicates with the section 16 by means of a nipple 20 near its bottom,

and the section 5 communicateswith the 'tubular structure by means of an interiorly threaded opening 21 into which the pipe 5 is threaded, and -it will be noticed that the pipe 5 is: spaced apart from the wall of the Specification of Letters Patent. Patented Apr; 19, 1921. V

blow-out pipe 15 is connected with the elf how, the blow-out pipe extendingapproxi- '8 is conical to form a valve seat, and the .of the top of the section 17, the two sections and the; upper end of the tubular section 18' I is interiorly threaded to receive a screw plug 19, which secures the sections together,

pipe 1 to provide an annular passage between the said pipes.

22, and the latter to receive a washer 23. The tubularstructure 18 is exteriorly reduced to form an'annular shoulder on which the washer 23 rests, and the washer is spaced above the ring, as clearly shown in Fig. 4. The internal diameter of the ring 22 is greaterthan that of the tubular structure annular opening between the tubular structure and the lnner edgeof the ring. The

The abutting edges of the sections 16 and 17 are rabbeted, as ,shown, the former section to receive a ring so that there is provided a relatively large section 17 of the casing is cut away at the edge that abuts the section 16, at the oppo site, side from the entrance point of the pipesl and 5, to form an arc-shaped outlet 24 for the burning gases: This outlet as indicated in Fig. 3 is. approximately;v 120 in length, and it will be noticed referring to Figs.'4 and 5 that the washer 23 has an areshaped series of openings 25 on its inner being duly installed and ready for service,

washer 23 also has a notch 26 in its periph: eral edge which is adapted to engage a stop in the rabbet of the section 17 to prevent angular movement of the washer with respect to the section. 1

The operation of the device is as, follows:

To start the improved burner, the burner steam is first admitted to the burner, the steam passing'th rough the pipe-1 into the chamber 27 below the washer 23, and this steam escapes through the slot or passage 24. A piece of burning waste is held in the furnace and near the nozzle and the oil under suitable pressure is admittedto the burner by way of the pipe 5, passing into the tubular structure 18 and out through radial openings 28 into the chamber 29 which is above the washer 23. This oil passes down through the openings 25 mixes with the steam and is ignited by the burning Waste. i "It will be noted that the steam and oil pressure oppose each other in the burner head and because of this fact the burner is practically self-regulating in its operation. Any rise inboiler pressure reacts through form boiler pressure even with a variation in load. The burner may be easily cleaned of reservoir for the oil, and is kept full of oil.

This oil is heated to a high degree by the inrushing steam in the chamber. 27, and the oil passes through the washer 23 in a very expanslve COnCl1f/10I1, contacting with the outgoing steam, just within the slot or parsage 24:.

It will be noticed-referring to Fig. 1 that the openings 25 are abovethe 'imperforate 7 portion of the ring 22.

The size of the openings 25 greatly influences the combustion. When the openings are large and few in'number, the combuF- j tion is violent in character and explosive,

- vibrating furnace walls and other structures in the vicinity. On the other hand when small openings are used the combustion is comparatively quiet and vibration is reduced to a minimum. Hence,a large number of small openings is provided which insures not only perfect" combustion but a broad fan-shaped flame from the burner head 1617. the burner on the oil supply and'retards 7 it while a drop in boiler pressure increases 7 the fl0w, thereby the tendency of the burner, all things beingequa'l, is to maintain a uniwithin the steam pipe 31, and the burner head. indicated at 32,.is on the fuel feed that burns quietly and does notjar the fur-'.

or oil pipe. This'head, as shown, is aclosed' casing having an arc-shaped series of openings'28 through which the oil'is delivered, the steam being delivered through the pipe 31. With this arrangement the'steam pipe is open, thespace between the pipes forming an annular chamber for the steam and the outlet for the steam is reduced by the I head so that there is some choking or increase of pressure at this point. Hence, the regulation of the feed will be 'in'the "same manner as in the construction shown in Fig. 1. An increase of boiler pressure will decrease the fuel" feed. With thisarrangement, the same arrangement'ofvalves and piping is used as shown-in Fig. 1, the burner head 32 taking the place of'the I claim: g 1; A burner head comprlslnga substantially cylindrical casing consisting of upperv and lower abutting sections, the lower section having a tubular member extending axially thereof and abutting theouter end of the upper section, said upper section having an opening registering with the bore of the tubular member, a plug passing through the opening and having threaded engagement with the tubular "mem'ben'said tubular member having a lateralnipple for V the casing.
